[PATCH] btrfs: move struct btrfs_ioctl_defrag_range_args from ctree.h to linux/btrfs.h
include/uapi/linux/btrfs.h is a more logical place to put the struct
btrfs_ioctl_defrag_range_args as it is being used by the
BTRFS_IOC_DEFRAG_RANGE IOCTL which is defined in that file.
Additionally, this is where the btrfs-progs defines that struct. Thus
this patches reduces the gap between the btrfs-progs headers and the
kernel headers.
